Cisco 10000 Series Four-Port

OC-3/STM-1c ATM Line Card

The Cisco 10000 Series Four-Port OC-3c/STM-1c Asynchronous Transfer Mode (ATM) line card provides both the performance and the density to scale networks efficiently and reliably. It features a high-performance segmentation and reassembly (SAR), adapted for various applications including advanced traffic management, cell scheduling, and integrated buffer management. By mapping IP class of service (CoS) to ATM quality of service (QoS) on the Cisco 10000 Series ATM line cards, the flow of mission-critical data can be effectively managed across heterogeneous IP and ATM networks.

•Per-virtual circuit and per-virtual path traffic shaping—The Cisco 10000 Series OC-3c/STM-1c ATM Module supports both per-virtual circuit and per-virtual path traffic shaping, providing flexibility and control over every virtual circuit and virtual path configured. Per-virtual circuit and per-virtual path traffic shaping allows bursts of traffic to conform to a predetermined contract, ensuring that excessive traffic from one virtual circuit does not incur data loss on other virtual circuits. This function is very important when connecting to an ATM WAN or public ATM network, where ATM switches may discard excessive traffic at the point of ingress.

•Standards-based ATM implementation for interoperability—The OC-3c/STM-1c ATM module is a standards-based ATM interface, allowing customers to integrate the Cisco 10000 Series into existing ATM networks. By implementing a standards-based version of ATM, Cisco ensures that customers will be able to easily and quickly integrate the Cisco 10000 Series into their current ATM network. Further, by using standard Operations, Administration, and Management (OA&M) F4 and F5, customers will enjoy lower management and administrative expenses and improved overall manageability.

•Supports up to 32,000 PVCs per module; up to 61,500 PVCs per platform; up to 32,000 UBR PVCs; up to 2000 nrt-VBR PVCs on the leased-line Cisco IOS® trains, beginning with Version 12.0(20)ST; up to 61,500 virtual circuits per platform; up to 8000 virtual circuits per port on the broadband aggregation Cisco IOS trains, beginning with Version 12.2(15)BX

Packet Layer Features

•Supports all IP routing protocols

•Supports application of QoS (Priority Queuing/CBWFQ, Weighted Random Early Detection [WRED], committed access rate [CAR]) to each nrt-VBR PVC, and to all UBR PVCs as a group using Cisco modular command-line interface (CLI)

–Supports ATM cell loss priority (CLP) bit

•Supports multicast

•Supports access control lists (ACLs)

•Supports Multiprotocol Label Switching (MPLS)

–Frame mode MPLS over ATM

–MPLS Cell mode with LC-ATM support. This value-added feature allows service providers with existing ATM backbone to upgrade their switches with label switch controller to support the MPLS control plane. It is a great value proposition, enabling new services to be provisioned over the infrastructure while protecting the investment.
